Mount the , for lack of better term wing /downforce device to the suspension to apply downforce directly . This allows for a softer springs -> better handling.
Im thinking somekind of sail on the bottom of the car that when you getting excess of airflow underneath of your air dam indicating lift, the airflow would push on the cell pushing and turn pushing a lever that would add pitch/AOA to the front wing. Kind of like a self deploying countermeasure. kind of like the roof Flaps in NASCAR but in a whole different context.
Mechanical force under the car versus the force on the wing above the car maybe too far away from each other. this can be solved with two servos. the first Servo can be the smallest one you can find you're only interested in the potentiometer and the ability to add a linkage. the second Servo would control the wing receiving its commands from the first servo having its potentiometer wired in place of the second servo. Considered an electro mechanical leverage.
another potential means of controlling this undesired vertical movement is with another pair of gyros to control the front wing and rear wing independently
